Be it known that I, EMIL LASER, a citizen of the United States, residing at Paterson,

in the county of Passaic and State of Newv Jersey, have invented certain newv and useful Improvements in Carpenters Work Supports, of which the following is a specification. l

This invention relates to ldevices for supporting a door, window sash or other similar work while resting on the floor in an upright position while an edge thereof is being planed, asin fitting the door etc. yto its opening. The object of the invention is to provide a simple and eihcient support of this class which the carpenter can use with facility by simply setting the support in place in some convenient building opening, as the opening. for which the door to be planed is designed.

The invention consists in certain novel combinations of parts substantially as herein shown and described and finally embodied in the appended claims.

In the drawing,

Fig. 1 shows a door opening, with the support in place holding a door to be planed, which appears in section;

Fig. 2 is a front elevation and Fig?) a plan of the support; v

Fig. 4 is a `vertical sectional view taken at one side of one of the clamping devices;

Fig. 5 is a front elevation, showing how the support may also be used for other purposes;

Fig. 6 is a vertical section on line 6-6` of Fig. 5; and

Fig. 7 shows a detail of Figs. 5 and 6.

l in Fig. l represents a door opening, the inner sides or opposing vertical faces of which are indicated at 2; The improved support is adapted to be fitted to the door opening, spanning the same and .being held in position by bearing against the inner sides Q thereof. For this purpose the support is constructed as follows:

3 3 designates two members in the form of fiat strips arranged face to face and parallel with each other, each preferably hav? ing an outer enlarged end 3a which is shod with a cushion of rubber 3b or other niaterial -which when the support is arranged as shown in Fig. 1 will obtain good frictional grip on the side 2 of the door opening.

The members are slidable on each other longitudinally and to confine them to such 17,1925. Serial No. 56,867.

movement each has on its relatively inner end portion, and as at 41,a clip 4 member. These confining means are preferable because they afford a certain added rigidity to the support when introducing it into and also when in operative position in the door opening. Y

Each member 3 has a longitudinal slot 5, such slots being in registry with each other.

Clamping devices are provided which both clamp the two members 3 in the position to which they are adjusted and also afford cheek portions between which the door is adapted to be received and held upright while being planed. The cheek portion of each device is indicated at Ggthese portions are both arranged at the same side of the support, or so as to bear againstone of the members. Each has a threaded shank 7 which penetrates both slots of the members and protrudes therefrom. On the protruding threaded end of each shank is a washer 8 and a nut 9. Y

In using the device to support a door while planing the latter the carpenter forces the Bferably pinned thereto, lw ich embracesthe other members apart so that their over-all length is a Jtrifle greater than the width of the door opening and then clamps them in their thusadjusted position by means of one of the Vclamping devices. He then sets the other clamping device the proper Vdistance from the first so that'. the door may be received fairly snugly between the cheek portions 6, whereupon he establishes this clamping -device in clamping relation to the members. He then places the device in the door opening so as to span the same and then whileV holding one end in fixed position, abutting the side of jamb of the'opening, he slides the other end over the surface of the oppositev side of the door opening until the support is horizontal. Thereby the device will be firmly fixed in position and will afford a rigid support for the door while being planed. Thus a firm support for the door,=

which is held by the supportvas shown in Fig. l while being planed, is afforded.

The support may also be used for other purposes, as in Figs. 4 to 6 where a clamp of well-known type is shown adapted to hold a saw while being filed and which it is necessary to describe only by stating that a is an elongated frame to rest on some horizontal support (and carrying the sawclamp a2), and a3 a bent arm depending therefrom and having tapped into it a thumb-screw a4 to coact with the frame, clamp-fashion, to grip the support. When this saw-clamp is to be fitted to my support I preferably provide an adapter l0 in the form of a block having three arms which receive the members 3 3 in the manner shown best in Fig. 6. Against the topv and bottom surfaces of this adapter bear the frame a and thumb-screw a4 when the latter is screwed up to obtain clamping action, while the sawclamp as a whole is kept from skewing around a vertical axis (through the thumbscrew) by contact of the cheek portions 6 with a vertical face of the saw-clamp.

One underlying novel feature of my device is that the two clamping devices for the members 3*?) of the support also afford means to receive the work. Another underlying novel feature consists in the employment, with the members 3-3 slidable on each other rectilineally to an inlinite number of positions, of a plurality of clamping devices for said members spaced from each other lengthwise of their path of sliding movement, whereby the device may be adj usted first to a little greater length than the width of the door opening and then forced as described from an initially inclined to a substantially horizontal or jammed relation to the sides of the door, thus distinguishing from known supports of this class in which the members are pivoted together and are forced into operative relation to the door opening by a toggle action.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is:

l. In a support for the purpose described, the combination of a pair of members each adjustable slidably and substantially rectilineally on the other and respectively adapted to bear against the inner sides of a building opening and be thereby supported, and a pair of devices for elampingsaid members in the position to which they are. adjusted having` co-acting work-holding cheek portions projecting from said support, one of said devices being adjustable toward and from the other substantially parallel with the path of adjustment of said members with respect to each other.

2. In a support for the purpose described, the combination of a pair of members having registering slots and each adjustable slidably on the other substantially lengthwise of said slots and respectively adapted to bear against the inner sides of a building opening and be thereby supported, and a pair of devices for clamping said members in the posit-ion to which they are adjusted having eo-acting work-holding cheek portions projecting from said support, one of said devices penetrating the slots and being adjustable lengthwise thereof toward and from the other.

3. In a support for the purpose described, the combination of a pair 0f elongated members each adjustable slidably on the other lengthwise thereof and respectively adapted to bear against the inner sides of a building opening and be thereby supported, means on the relatively inner end portion of each member to confine the other member during adjustment to substantially longitudinal movement, and devices arranged on the support and having co-acting work-holding cheek portions projeetingl therefrom, one o'l said devices being a clamp to'clamp said members in the position to which they are adjusted and one of said devices being adjustable on the support substantially parallel with the path of adjustment of said members on each other.

In testimony whereof I affix my signature` EMIL LASER.
